' The current rule weight may have been in standing long before electrics were thought of but electrics were taken into consideration because they are specifically stated in the rule. '

Hi Scott,
I will try to get this right.
At FAI / International level it went something like this ;
- The distant past - irrelevant now.
- The 60/120/2x2 rule.
- The unlimited engine rule.
The 5Kg rule applied all the while.
- 2003 Jason Shulman flew electric in the WC's Poland. My understanding is that he was weighed without the batteries (his fuel). No biggie. At that time others ,perhaps not Int,, pilots, were also getting into E power.
- Knee jerk reaction by the F3A Sub-committee, perhaps with some pressure from some influences,and we got that what we have today - weigh with batteries (but you can remove the electrons). This was 2004/5 cycle I believe.
- Since then we have people defending the position in which they find themselves and perhaps still some pressure from some influences.
- 2009/10 cycle ,I think, the 1% tolerance rule
